Note: The following screens are available for the GS2200-24P model only. Some
features are only available for the Fast Ethernet ports (1 to 24).
Your Switch supports IEEE 802.3af Power over Ethernet (PoE).
A powered device (PD) is a device such as an access point or a switch, that
supports PoE (Power over Ethernet) so that it can receive power from another
device through a 10/100Mbps Ethernet port.
In the figure below, the IP camera and IP phone get their power directly from the
Switch. Aside from minimizing the need for cables and wires, PoE removes the
hassle of trying to find a nearby electric outlet to power up devices.
Figure 44 Powered Device Examples
You can also set priorities so that the Switch is able to reserve and allocate power
to certain PDs.
Note: The GS2200-24P is compatible with ZyXEL's PPS250 power module. The
PPS250 provides additional external PoE power budget on top of the internal
power budget of the GS2200-24P. Refer to the User's Guide of the PPS250 for
more information.
Note: The POE (Power over Ethernet) devices that supply or receive power and their
connected Ethernet cables must all be completely indoors.
Note: The RPS connector port at the back panel of the GS2200-24P and RPS
connector cable should only be used with the PPS250. Do not insert other
connector cables to the RSP connector port of the GS2200-24P or the PPS250.

Click Apply to save your changes to the Switch's run-time memory. The
Switch loses these changes if it is turned off or loses power, so use the
Save link on the top navigation panel to save your changes to the non-
volatile memory when you are done configuring.
